md5sum: Output format error on files with backslash in their names

[W. L.]

Dear Team,

using md5sum on files with a backslash in their filenames 
gives an error in the output file format: A waste backslash
is output at the beginning of the line.

Also the backslashes themselves are quoted: Bug or feature?

Please check following example:

> md5sum ../div/Üble\ Filenamen/*
\45bb8963e53c01e2fd6f926bc15f0553  ../div/Üble Filenamen/with\nLinefeed
\d41d8cd98f00b204e9800998ecf8427e  ../div/Üble Filenamen/with \\ Backslash
\d41d8cd98f00b204e9800998ecf8427e  ../div/Üble Filenamen/with \\\\ Backslashes
a6a218b4d55f251551f21ac351bded8e  ../div/Üble Filenamen/äöü?
...

Best regards,
W. Limmer
